1. Check your keyboard layout:
* Windows: Go to Settings > Time & Language > Region & Language. Make sure your preferred language is set correctly. You can also switch between keyboard layouts using the language bar at the bottom right of your screen.
* Mac: Go to System Preferences > Keyboard > Input Sources. Check if your preferred language is selected and if there are any additional keyboard layouts enabled.
2. Check your keyboard settings:
* Windows: Go to Settings > Time & Language > Language > English (United States) > Options > Keyboard. Look for any special keys that might be affecting your question mark.
* Mac: Go to System Preferences > Keyboard > Input Sources. Check the "Keyboard" tab to see if any keys are remapped.
3. Look for key conflicts:
* Are you using any special keyboard software or programs that might be interfering with your keyboard layout? Try disabling them temporarily to see if it solves the problem.
* If you have multiple external keyboards connected, try disconnecting them one by one to see if any of them are causing the issue.
4. Test the keyboard:
* Try typing the question mark using the "Shift" key and the "slash" key (/) on your keyboard. This often works as a temporary solution, especially if the issue is caused by a key sticking or a software bug.
5. Restart your computer:
* A simple restart can sometimes fix temporary software glitches.
6. Update your drivers:
* Outdated keyboard drivers can sometimes cause strange behavior. Check for driver updates on your computer's manufacturer website or through the device manager (Windows) or system preferences (Mac).
7. Check the keyboard itself:
* Examine your keyboard for any dirt, debris, or damaged keys. If the key is physically stuck or damaged, you might need to clean it or get a replacement.
8. If all else fails:
* If you've tried all these troubleshooting steps and the problem persists, you might need to consult a computer technician for further assistance.
